Embodiment 1

[0036] Example 1: Preparation method: According to the designed formula, add the weighed original medicine, emulsifier, wetting agent, thickener and water into the sand mill cylinder, stir evenly, and disperse under high-speed stirring for 30 minutes, and stop pre-dispersion. Add the sanding medium (glass beads) and defoamer, start the motor, and start sanding. After 2 to 4 hours, stop sanding, filter, remove glass beads, add other additives, antifreeze and stabilizer to mix, to obtain a suspension.

[0037] How to use: Dilute with water at 70 g / 667m2 and spray.

Embodiment 2

[0038] Example 2: The weight ratio of each component of the microemulsion type compound

[0039]

[0040] Preparation method: phase inversion method. Fully dissolve and mix the original medicine, solvent and emulsifier into a uniform and transparent oil phase. Under stirring, slowly add distilled water or deionized water to form a W / O type emulsion, and then stir and heat to make it rapidly phase inversion O / W type microemulsion is formed, cooled to room temperature, standing and filtered to obtain O / W type microemulsion.

[0041] Usage: Dilute with water at 70 g / 667m2 and spray.

Embodiment 3

[0042] Example 3: The weight ratio of each component of the water dispersible granule type compound agent

[0043] Component weight percentage weight percentage weight percentage

[0044] Emamectin benzoate 0.5% 1% 3%

[0051] Preparation method: dry method. The original medicine and various additives are mixed uniformly, and then pulverized to the specified fineness by airflow to make a wettable powder. Extrusion granulation. The wettable powder and a certain amount of water (or with a binder) are added to the kneader and kneaded at the same time to form a plastic material with a moisture content of 15-20%. Finally, the material is sent to the extrusion granulator for making Granules are dr...

Abstract

A diflubenzuron and emamectin benzoate complex agent is prepared from emamectin benzoate and diflubenzuron according to a weight ratio of 1:1 to 1:40, and preferably the weight ratio is 1:20. The pesticide composition can be made into suspending agent, micro-emulsion, and water dispersible granule through methods known by those skilled in the art. The diflubenzuron and emamectin benzoate complex agent has the advantages of good insect control effect and low application cost, and is capable of being wildly popularized and used.

Description

Technical field [0001] The invention relates to a synergistic pesticide composition, in particular to a synergistic pesticide composition containing diflubenzuron and emamectin benzoate. Background technique [0002] Diflubenzuron: (Hexaflumuron) Diflubenzuron is a benzoyl phenylurea insecticide, which is similar to Diflubenzuron III. The insecticidal mechanism is also by inhibiting the synthesis of insect chitin synthase. This inhibits the synthesis of chitin in the epidermis of larvae, eggs, and pupa, and makes insects unable to ecdymal body deformity and death. After the pests eat, they cause cumulative poisoning. Due to the lack of chitin, the larvae cannot form new epidermis. The pupae are blocked; the adults are difficult to emerge and lay eggs; the eggs cannot develop normally, and the hatched larvae lack hardness and die, which affects the entire generation of pests. This is the advantage of diflubenzuron. The main mode of action is stomach poisoning and contact killing. ...
